Overall, 60 patients (Total\u2009=\u2009120 implants) from the archive records of the Prosthodontics Department, Faculty of Dentistry, Mansoura University, with ages ranging from 40 to 60 (mean age 50), were included in the study. Group I (control): Overall, 30 patients who would be delivered mandibular implant overdenture using conventional locator attachments. Group II (study): Overall, 30 patients who would be delivered mandibular implant overdenture using RTx locator attachments. After the placement of the mandibular overdenture (T0), 6\u2009months (T6), 12\u2009months (T12), and 3\u2009years (T3) later, the marginal bone loss (MBL) was assessed. Prosthetic complications were evaluated for both groups 3\u2009years after prosthetic delivery.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Result<\/jats:title>\n                    <jats:p>\n                      A statistically significant increase (\n                      <jats:italic>p<\/jats:italic>\n                      \u2009=\u20090.000) was found in MBL scores at all observation times between both groups.
